[Texmap] Memory leak when closing a tab
https://bugs.webkit.org/show_bug.cgi?id=112127

When closing a tab, if there are any updates pending in CoordinatedGraphicsScene's
render queue, the scene is not freed because reference count of m_scene is not zero.

No new tests.

* platform/graphics/texmap/coordinated/CoordinatedGraphicsScene.cpp:
(WebCore::CoordinatedGraphicsScene::detach): When bind updates in CoordinatedGraphicsScene,
the reference count of m_scene is increasing, if m_renderQueue is not empty
before closing tab, then m_scene is never freed.
Hence, when closing tab, need to clear m_renderQueue explicitly in order to
destroy m_scene.
